The ∆-resonance in a finite volume#1
We study the extraction of ∆-resonance parameters from lattice data for small quark masses, corresponding to the case of an unstable ∆. To this end, we calculate the spectrum of the correlator of two ∆-fields in a finite Euclidian box up-to-and-includingO(ǫ) in the small scale expansion using infrared regularization. On the basis of our numerical study, we argue that the extraction of the param...
متن کاملBlood Flow Simulation in an Aorta with a mild coarctation Using Magnetic Resonance Angiography and Finite Volume Method
Coarctation of the aorta is one of the five main congenital cardiovascular failures, accounting for 6–8 percent of these failures. This research aimed to simulate the blood flow of a seventeen-year-old male teen with a mild coarctation at one-third of his aorta's descending branch. The simulation was performed by extracting the domain and the input pulsatile velocity signal as the boundary cond...
متن کاملA development in the finite volume method for the crack growth analysis without global remeshing
Crack growth analysis has remained one of the challenging problems in the fracture mechanics of structures. On the other hand, the fatigue crack growth is a common phenomenon in the components of structures like airplanes, navies and fluid storages where the fracture due to crack should be considered in the design of these structures. In this paper, the finite volume method (FVM) is extended fo...
متن کاملThe mass of the ∆ resonance in a finite volume : fourth - order calculation February 13 , 2009
We calculate the self-energy of the ∆(1232) resonance in a finite volume, using chiral effective field theory with explicit spin-3/2 fields. The calculations are performed up-to-and-including fourth order in the small scale expansion and yield an explicit parameterization of the energy spectrum of the interacting pion-nucleon pair in a finite box in terms of both the quark mass and the box size...
